BOAT.

Application filed May 8, 1914.

T 0 all whom it may concern Be it known that we, JOHN PIVARCHY andGasman Prvancrrv, citizens of the United States, residing at Uniontown,in the county of Fayette and State of Pennsylvania, have invented newand useful Improvements in Boats, of which the following is aspecification.

This invention relates to boats and particularly small boats such as areadapted to be propelled by oars and the like, the object of the presentinvention being to provide in connection with a boat of the classreferred to, a pair of buoyant floats of the catamaran type, said floatsbeing hingedly connected to the opposite sides of the hull of the boatand adapted to fold upwardly and downwardly for the purpose ofpreventing the boat itself from sinking even though entirely filled withWater and containing passengers.

A further object of the invention is to so construct and arrange thefloats in relation to the boat as to adapt them to be folded under thebody of the boat and inside of the vertical planes of the gunwales so asto enable the boat to becompactly stored and shipped.

\Vith the above and other objects in view, the invention consists in thenovel construction, combination and arrangement of parts, as will behereinafter more fully described, illustrated and claimed.

In the accompanying drawings :Figure 1 is a plan view of a boatembodying the present invention. Fig. 2 is an end view of the same. Fig.3 is a similar view showing the floats swung downwardly. Fig, 4 is avertical cross section in line with one of the hinges.

Referring to the drawings A generally designates a boat of the ordinaryconstruction adapted to be propelled by oars for which the usual oarlocks l are provided.

In carrying out the invention we employ a pair of floats designatedgenerally at B, said floats being elongated in a fore and aft directionand being also curved along their major axes so as to conform more orless accurately to the outer contour of the boat A. In the preferredembodiment of this invention each of the floats B is preferably of theinflatable type and made of rubber or its equivalent, the same beingairtight throughout and the opposite extremi- Specification of LettersPatent.

ties of each float being preferably pointed as at :2 so as to resemble acigar in shape.

Each float B is permanently attached to the side of the boat by means ofa plurality of hinges designated generally at G, each hinge comprisingan inner knuckle 3 carried by the boat and shown as formed on a knuckleplate lriveted or otherwise se cured to the side of the boat. Preferablyinner plates 5 are used in complemental relation to the plates l, theinner plates 5 bearing against the inside of the boat and being rivetedthrough the boat as shown at 6, said rivets firmly securing the outsideand inside plates together and making a good reliable construction. Theouter knuckle 7 of each hinge is bifurcated as shown at 8 to partiallyextend around the adjacent float, the upper section of said knucklebeing provided with an ofliset 9 forming a stop adapted to come againstthe outside plate 4 and limit the extent to which the float may be movedupwardly, thereby holding said float in its operative position whenupheld by the buoyancy ol' the water. The outer knuckle also comprises ahinged section 10 connected to the main section by the pivoted or hingedjoint 11 and both sections of the outer knuckle are provided withoutwardly extending cars 12 through which is inserted a clamp bolt 18.It will thus be seen that all of the outer knuckles have a stop forlimiting the upward movement of the float and also a strap whichsurrounds the float and holds the same against displacement. 'When theboat is in the water the floats automatically assume the positionillustrated in Fig. 2 and serve to materially stabilize the boat inrough 'water and also prevent any possibility of the boat sinking aslong as the floats which are air and water-tight remain uninjured.

When the boat is out of the water, the floats B are swung downwardlyunder the body of the boat as shown in Fig. 3 where they will lie withinthe vertical planes of the opposite sides of the boat at the greatestbeam or width amidships thus enabling the boat to be compactly stored onthe deck of a vessel or any other place, also adding to the ease oftransportation and shipment.

One or both ends of each float B may be made in the form of a solidblock 13 as indicated in Fig. t and provided with a central bore 1awhich communicates with an air inlet opening in the top of the float,said inlet opening being normally closed by means of a plug 16. Thisgreatly facilitates the inflation of the floats.

WVhat we claim is l. The combination with a boat, of a pair of floatsupporting hoops hinged to opposite sides thereof, floats at oppositesides of said boat elongated in a fore and aft direction, eachcomprising non-collapsible end sections held in said hoops, and anintermediate flexible collapsible and inflatable section terminallyattached to said end sections, and means on each of said hinged hoopsfor limiting the upward movement thereof relatively to the boat.

2. The combination with a boat, of a pair of floats supporting hoopshinged to opposite sides thereof, floats at opposite sides of said boatelongated in a fore and aft direction, and each comprisingnon-collapsible end sections held in said hoops, and an intermediateflexible collapsible and inflatable section terminally attached to saidend sections, and means on each of said hinged hoops for limiting theupward movement thereof relatively to the boat, one of thenon-collapsible end sections of each float being formed with aninflating passage.

In testimony whereof we aflix our signatures in presence of twowitnesses.
